What Part of Dr. No Don't You Understand?

In Dr. No, the first James Bond movie ever, I get that:

• His game is baccarat
• His name is Bond, James Bond
• His boss is M. His boss's secretary, Moneypenny, wants him
  
• He has a license to kill
• He carries a Walther PPK (although he prefers a Beretta)
• He drinks vodka martinis, medium dry, shaken not stirred
• He can fight, drive and love like nobody else
• He fights evil madmen who want to rule the world, usually from an undersea or underground lair
  

Dr. No sets up a lot of the iconic Bond themes, missing only Q and the gadgets. Compared to the next movie, From Russia with Love (which we will be watching as soon as Netflix gets more than 1 or 2 copies), it is a very mainstream Bond. A surprisingly complete snapshot of the mythos.

What I don't understand is why we had to wait more than half the movie to meet Ursula Andress.
